How a Factory Audit in Vietnam Works, and When It Is Worth Paying For

September 12, 2026

A factory audit answers one question: is this company what it says it is. It is the cheapest risk reduction available on a first order in Vietnam, and it is routinely skipped by buyers who then spend far more sorting out the consequences.

Third party audit firms in Vietnam commonly price by man-day, with published 2026 rates in the region of a few hundred US dollars per man-day, and most straightforward audits taking one day. Against a tooling deposit or a first order, that is a rounding error.

What an audit actually checks

A general factory audit covers five areas.

Legal and commercial standing. Business registration, the legal name on the license against the name on the quotation, export history, and whether the company you are talking to is the one that owns the building and the machines. This single check catches the most common surprise, which is that the “factory” is a trading office.

Equipment and capacity. What machines exist, how many, their age and condition, and whether they are the ones needed for your process. An auditor counts what is there rather than what is on the website.

Process control. Whether there is a documented flow from incoming material to final pack, whether inspection points exist, and whether records are kept. A factory that cannot show you a record of last month’s rejects does not have a process, it has habits.

Staffing and capability. Headcount by function, whether there is a quality function separate from production, and whether anyone can communicate in the language you will be writing in.

Working conditions and compliance. Hours, age verification, safety, fire exits, dormitory conditions where relevant. If you sell into markets or to retailers that ask for social compliance evidence, this is where a general audit becomes a social audit under one of the recognised schemes.

General audit, social audit and systems certification

These three get confused constantly.

A general or technical audit is commissioned by you, scoped by you, and reported to you. It answers whether this factory can make your product reliably.

A social compliance audit follows a published scheme, is conducted by an approved body and produces a report that your customers may accept as evidence. Factories that already hold a current social audit report will usually share it, which saves you commissioning one.

A systems certification such as ISO 9001 says a quality management system was audited against a standard at a point in time. It is a useful signal and it is not a statement that the factory can make your part well. Plenty of certified factories produce poor parts and plenty of uncertified ones produce excellent parts.

Ask for what each is for. Paying for a social audit when your problem is process capability is a common waste.

When in the project to run it

The useful sequence is:

1. Shortlist on capability, from quotes and files.
2. Video call and a documents check on the shortlist.
3. Audit the one or two you intend to use.
4. Deposit, tooling and production.
5. Inspection during production and before shipment.

Auditing at step three is the point where the information changes a decision. Before that, you are paying to audit candidates you will not choose. After that, the money is committed and the audit becomes a way to feel better rather than a way to decide.

Reading the report

Audit reports are long and the important parts are short. Three things matter:

The photographs. Look at the floor, not the machines. Material staged in order, labelled work in progress and a tidy rework area say more about process control than any certificate.

The gaps the auditor could not close. Every honest report has them: a record that was not available, a manager who was not on site. Those are the lines to follow up on, and a factory’s response to being asked is itself information.

The match to your product. A factory can pass every general criterion and still be wrong for you, because the equipment suits a different size or tolerance class. The audit scope has to name your process, or the report tells you the company is sound and nothing about whether your part will be.

What an audit does not do

It does not tell you the factory will still be good in six months, it does not commit the factory to anything, and it does not replace inspection of the goods you actually buy. A clean audit plus no inspection is a common and expensive combination.

Inspection is the other half, and it runs on a different logic. AQL inspection levels explained covers how goods get checked and what the numbers on an inspection report mean.

Under a turnkey contract

If one manufacturer carries your whole scope, the audit question widens: the company you audit may subcontract molding, plating or printing. Ask which steps are in house and which are not, and get the subcontracted steps named. A turnkey partner that is candid about what it subcontracts is usually more reliable than one that claims everything is in house. See what a turnkey manufacturing contract actually covers.

Scoping the audit so it answers your question

Audit firms will run a standard checklist if you let them, and a standard checklist answers standard questions. Half a page of scope from you makes the same money far more useful.

Tell the auditor what you are making and what worries you. If your product needs a specific process, ask for that process to be observed running, not just for the machine to be photographed. If your concern is capacity, ask for the current order book load and how your volume would fit. If it is quality systems, ask for the last three months of defect records and a traceability walk on one batch.

Three specific requests worth adding to almost any scope:

• Confirm the legal entity on the business licence matches the entity on the quotation and the bank details.
• Photograph the incoming material area, the rework area and the finished goods store.
• Name which production steps are subcontracted and to whom.

The third one catches more surprises than the rest of the checklist combined.

What to do with a report that is not clean

Very few reports come back perfect and a mixed report is not automatically a rejection. The useful move is to separate findings into three buckets.

Blocking. Wrong legal entity, no evidence of the claimed equipment, serious safety or labour findings. These end the conversation.

Fixable before the order. Missing documented procedures, no incoming inspection, no separate quality function. Ask what the factory intends to do and by when, then verify.

Accepted with a control. Findings you can live with if you add something on your side, usually an inspection at a point the factory does not currently check.

Send the findings to the factory and read the response carefully. A factory that engages, explains and commits to dates is often a better partner than one with a cleaner report and a defensive reply.

Send your project brief and we will match you with manufacturers that are used to being audited and will say plainly what they run themselves.
